The importance of lipids in cell signaling and tissue physiology is demonstrated by many CNS pathologies that involve deregulated lipid metabolism. One such critical metabolic event is activation of phospholipase A2 (PLA2), resulting in hydrolysis of membrane phospholipids and release of free fatty acids including arachidonic acid, a precursor for important cell-signaling eicosanoids. Reactive oxygen species (ROS, a product of arachidonic acid metabolism) react with cellular lipids to generate lipid peroxides, which degrade to reactive aldehydes (oxidized phospholipid, 4-hydroxynonenal, and acrolein) that covalently bind to proteins, altering their function and causing cellular damage. Dissecting the contribution of PLA2 to lipid peroxidation in CNS injury and disorders is challenging due to multiple forms of PLA2, diverse sources of ROS and lack of specific PLA2 inhibitors. This review summarizes the role of PLA2 in CNS pathologies including stroke, spinal cord injury, Alzheimer’s, Parkinson’s, Multiple sclerosis - Experimental autoimmune encephalomyelitis and Wallerian degeneration.
